Substituted quinazoline and pyrido-pyrimidine derivatives

ABSTRACT

The present application provides novel substituted quinazoline and pyrido-pyrimidine compounds and pharmaceutically acceptable salts thereof. Also provided are methods for preparing these compounds. These compounds are useful in co-regulating PI3K and/or mTOR activity by administering a therapeutically effective amount of one or more of the compounds to a patient. By doing so, these compounds are effective in treating conditions associated with the dysregulation of the PI3K/AKT/mTOR pathway. Advantageously, these compounds perform as dual PI3K/mTOR inhibitors. A variety of conditions can be treated using these compounds and include diseases which are characterized by inflammation or abnormal cellular proliferation. In one embodiment, the disease is cancer.

BACKGROUND

With the onset of cancers which are refractory to most conventional treatments, there is a need for new and effective chemotherapeutics. As details emerge about the molecular etiology of various cancers, new chemotherapeutics can be designed which affect one or more vulnerable targets associated with a given cancer at a sub-cellular level.

Certain cancers (and indeed other diseases of abnormal cellular growth) include those which are due to the dysregulation of one particular molecular signaling pathway in the body. Restoring regulation of that particular pathway to normal or near-normal levels can have a positive impact in treating the patient, including a reduction in tumor size or even putting the patient into remission.

For example, perturbations of the phosphoinositide 3-kinase (PI3K)/AKT/mammalian target of rapamycin (mTOR) signaling pathway are closely associated with the etiology of most solid tumors. The PI3K/AKT/mTOR pathway can be overactivated by a number of molecular effectors, including chemokines, the loss of INPP4B or PTEN expression, or by mutations in PI3K itself. Overactivation of this pathway can manifest in a number of molecular and morphological changes which are characteristic of tumorigenesis, including increased cell proliferation, survival and motility, and altered cell cycle entry. mTOR is a central regulator of cell growth which acts by controlling cellular protein translation. Several small molecules have been described as being mTOR inhibitors which are useful for treating cancers. PI3K is a heterodimeric enzyme that generates lipid second messengers, such as phosphatidylinositol-3,4,5-triphosphate (PIP3), that mediate signal transduction. PI3K enzymes regulate key signal transduction pathways controlling vital cell processes that are implicated in carcinogenesis, and include four isoforms; i.e., p110α, p110β, p110δ and p110γ. Specific mutations in p110α have been identified in various cancers. Several small molecules have been described as inhibitors of PI3K. Further, there are a number of compounds, including wortmannins and rapamycins, which have been shown to be highly potent and specific inhibitors of PI3K and mTOR, respectively.

Indeed, several recent compounds have been described as being useful in regulating the PI3K/mTOR pathway. For example, GDC-0941, PX-866, XL-147, BKM-120, and BAY 80-6946 are inhibitors of PI3K, whereas rapamycin, temsirolimus (CCI-779), everolimus (RAD001), ridaforolimus (deforolimus, AP23573, MK-8669), OSI-027 and AZD8055 are inhibitors of mTOR. However, intervention at a single point in a the PI3K/AKT/mTOR signaling pathway may not be as effective in treating solid tumors as targeting multiple pathway members. Administering multiple drugs to a cancer patient, each of which inhibit a certain target in the PI3K or mTOR pathway, carries its own risks in terms of increased drug load, potential toxicity, drug-drug interactions and the like. What remains in the art, therefore, is the need for single compounds which regulate the PI3K/AKT/mTOR pathway by targeting both PI3K and mTOR. Certain compounds recently described in the art, including BEZ-235, XL-765, GDC-0980, GSK-2126458, PKI-587, and PF-04691502, have been reported to target both PI3K and mTOR. However, the need remains for compounds with this type of dual activity profile to be developed and approved for clinical use.

Methods useful for making the compounds of formula (I) are set forth in the Examples below and generalized in Schemes 1-15.

The following methods outline the synthesis of the compounds of formula (I). The following examples are presented to illustrate certain embodiments of the present invention, but should not be construed as limiting the scope of this invention.

Scheme 1 depicts a first synthesis of the boronic acid pinacol ester intermediate compound [1]. Specifically, a 4-nitrobenzoic acid [A] is converted to the corresponding amide [B] using an amine such as R⁷R⁸NH, a coupling agent such as EDCI.HCl, DCC, HBTU, or HATU, an additive such as HOBt or HOAt, a base such as TEA or DIPEA and solvent such as DMF, THF, or DCM. In one embodiment, the amine may be NH₃, NH₂CH₃, NH(CH₃)₂, morpholine, piperidine, 1-methyl-piperazine and N(CH₃)₂CH₂CH₂N(CH₃)₂, among others. Typically, this is performed at rt such as about 25 to about 30° C. for about 10 to about 15 h such as about 10 h. The 4-nitro amide [B] is then reduced to the corresponding amine [C] using H₂ and a catalyst such as Pd/C 10%, PtO₂, or Pd(OH)₂. Typically, the reduction is performed under pressures such as 60 psi, in a solvent such as MeOH, dioxane, or ethylacetate, for about 3 to about 5 h such as about 3 h. Amine [C] is then converted to urea [D] using an appropriately substituted isocyanate such as 4-bromophenyl isocyanate. This reaction is typically performed in the presence of a base such as TEA or DIPEA and solvent such as CH₂Cl₂, CHCl₃, or THF at about rt such as about 25 to about 30° C. for about 5 to about 15 h such as about 12 h. As one alternative method, amine [C] can be converted to the corresponding 2,2,2-trichloroethyl carbamate and then reacted with an appropriately substituted aniline or pyridinyl amine, to produce the desired urea [D]. For example, amine [C] would typically be treated with 2,2,2-tri-chloroethyl chloroformate in the presence of a base such as triethylamine or DIPEA, in a solvent such as CH₂Cl₂, CHCl₃, or THF, at temperatures such as 0° C. to about 30° C. for about 30 minutes to 5 hours, to produce the 2,2,2-trichloroethyl carbamate intermediate. Then the 2,2,2-trichloroethyl carbamate intermediate is typically reacted with the aniline or pyridinyl amine in the presence of a base such as triethylamine or DIPEA, in a solvent such as toluene, 1,4-dioxane or THF, at about room temperature up to elevated temperatures such as about 110° C. for about 1 to 16 hours. This alternative two-step procedure provides the urea [D]. Intermediate boronic acid pinacal ester [1] is then formed by reacting urea [D] with bis(pinacolato)diboron. This reaction may be performed in the presence of a weak base such as KOAc, palladium catalyst such as Pd(dppf)Cl₂.DCM or Pd(dppf)Cl₂, in a solvent such as 1,4-dioxane or DMF. Desirably, the reaction is performed at elevated temperatures such as the reflux temperatures of the solvent. In one embodiment, this reaction is performed at about 80 to about 120° C. for about 2 to about 15 h. In another embodiment, this reaction is performed at about 110° C. for about 10 h.

Scheme 1A depicts the synthesis of the boronic acid intermediate compound [1A]. In one embodiment, 4-nitrobenzoic acid [A1] is converted to the corresponding amide [B1] using R⁷R⁸NH and 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide hydrochloride (EDCI.HCl), HOBt and TEA in DMF at rt for about 10 h. The 4-nitro amide [B1] is then reduced to the corresponding amine [C1] using H₂ and Pd/C 10% at 60 psi, in MeOH for about 3 h Amine [C1] is then converted to urea [D1] using 4-bromophenyl isocyanate in the presence of TEA in CH₂Cl₂ at about rt for about 12 h. Intermediate boronic acid pinacol ester [1A] is then formed by reacting urea [D1] with bis(pinacolato)diboron in the presence of KOAc, Pd(dppf)Cl₂.DCM, 1,4-dioxane at 110° C. for about 10 h.

Scheme 2 provides a second synthesis of the boronic acid pinacol ester intermediate [1]. Intermediate compound [C] is prepared as described in Scheme 1. In a separate reaction, an appropriately substituted aniline such as 4-bromo aniline [H] is converted to the corresponding carbamate [J] using 2,2,2-trichloroethyl chloroformate or trichloromethyl chloroformate and a base such as TEA or DIPEA. Typically, this conversion is performed in the presence of a solvent such as DCM, CHCl₃, or THF at reduced temperatures, i.e., about 0° C. to rt, for about 2 to about 4 hours, for example about 4 h. It will be recognized by those skilled in the art that in certain cases, when the desired aniline [H] is not commercially available, it can be prepared by methods known in the art. For example, 4-bromo-2,3-difluoroaniline is prepared by reaction of 2,3-difluoroaniline with tetrabutylammonium tribromide, as described in Int. Pat. Appl. WO2010091272 (2010). An amine such as intermediate compound [C] is then coupled with carbamate [J] in the presence of a base such as TEA or DIPEA and in a solvent such as 1,4-dioxane, toluene, or mixtures thereof to form urea [K]. Typically, the coupling is performed at elevated temperatures, i.e., about 90 to about 110° C. such as about 95° C., for about 10 to about 15 h, such as about 10 h. Reaction of urea [K] with bis(pinacolato)diboron in the presence of a catalyst such as Pd(dppf)Cl₂.DCM or Pd(dppf)Cl₂ provides intermediate [1]. Typically, this reaction is performed in the presence of a base such as KOAc, a solvent such as 1,4-dioxane or DMF, and at elevated temperatures such as about 80 to about 120° C., such as about 110° C., for about 2 to about 15 h, such as about 10 h.

Scheme 2A provides a synthesis of boronic acid intermediate [1B]. Intermediate compound [C1] is prepared as described in Scheme 1A. In a separate reaction, 2-fluoro-4-bromo aniline [H] is converted to the corresponding carbamate [J1] using 2,2,2-trichloroethyl chloroformate and TEA in the presence of DCM at about 0° C. to rt for about 4 h. Intermediate compound [C1] is then coupled with carbamate [J1] in the presence of TEA and 1,4-dioxane at about 95° C., for about 10 h to form urea [K1]. Reaction of urea [K1] with bis(pinacolato)diboron in the presence of Pd(dppf)Cl₂.DCM, KOAc, and 1,4-dioxane at 110° C. for about 10 h provides intermediate [1B].

Scheme 3 provides a third route to intermediate [1]. In this route, an appropriately substituted aniline, such as 4-bromoaniline [H], is reacted with an appropriate isocyanate such as ethyl 4-isocyanatobenzoate to form the corresponding urea [M]. Typically, this reaction is performed in a solvent such as DCM or CHCl₃, base such as TEA or DIPEA, at about rt, such as about 25 to about 30° C., for about 3 to about 6 h, such as about 3 h. The ester moiety of urea [M] is then hydrolyzed to the corresponding benzoic acid [N] using a base such as LiOH.H₂O or NaOH in one or more solvents such as EtOH, THF, and/or water over a period of about 6 to about 12 h, such as about 6 h. Conversion of the benzoic acid [N] to benzamide [0] is performed using an amine such as R⁷R⁸NH, with coupling agents such as EDCI.HCl, DCC, HATU, or HBTU, and HOBt or HOAt. Typically, benzamide [0] is prepared using a base such as TEA or DIPEA, in solvent such as DMF, THF, or DCM, at rt, such as about 25 to about 30° C., over a period of about 10 to about 15 h, such as about 10 h. Conversion of benzamide [0] to intermediate [1] is performed using the reagents and conditions described in step e of Scheme 2.

In one embodiment, Scheme 3A provides a third synthesis of intermediate [1B]. In this route, 2-fluoro-4-bromoaniline [H1] is reacted with ethyl 4-isocyanatobenzoate in DCM and TEA at about rt for about 3 h to form the corresponding urea [M1]. The ester moiety of urea [M] is then hydrolyzed to the corresponding benzoic acid [N1] using LiOH.H₂O, in EtOH, THF, and water over a period of about 6 h. Conversion of the benzoic acid [N1] to benzamide [O1] is performed using R⁷R⁸NH, EDCI.HCl and HOBt in the presence TEA and DMF at rt over a period of about 10 h. Conversion of benzamide [O1] to intermediate [1B] is performed using the reagents and conditions described in step e of Scheme 2A.

It will be apparent to those skilled in the art that compounds of formula (I), where M is amide group —N(R⁹)—C(O)R¹⁰, can be synthesized by methodology similar to those methods described above, wherein M is an amide group of type —C(O)NR⁷R⁸. For example, the boronic acid pinacol ester intermediate compounds where M is amide group —N(R⁹)—C(O)R¹⁰ can be prepared by methods similar to those described in Schemes 1, 2 and 5. For example, Scheme 9 depicts an example of the synthesis of boronic acid pinacol ester intermediate compound [2]. Specifically, a 4-nitrobenzoic acid [A2] is converted to the corresponding amide [B2] by reaction with an acyl chloride R¹⁰COCl, in the presence of a base such as TEA or DIPEA, and using a solvent such as DMF, THF, or DCM, typically at temperatures of 0 to 25° C., for about 30 minutes to 24 hours such as 12 hours. The nitro-phenyl intermediate [B2] that is formed (R⁹═H in this case) is then reduced to give the amino-phenyl intermediate [C2], for example by using hydrogen over catalytic 10% Pd/C, in a solvent such as methanol or ethanol, for about 1 hour to 24 hours such as 12 hours. The intermediate [C2] is then converted to the urea [D] by methods described in Schemes 1 to 5 above, and urea [D2] is then converted to the desired boronic acid pinacol ester compound [2] by methods described in Schemes 1, 2 and 5. Additional compounds [2] are prepared from other intermediates [C2] that can be synthesized by methods known to those skilled in the art, for example from halogen compounds [E]. As a specific example, 1-(4-aminophenyl)pyrrolidin-2-one is used for the preparation of compounds of formula (I) where M is an amide group of type —N(R⁹)—C(O)R¹⁰, wherein R⁹ and R¹⁰ are joined such that —R⁹-R¹⁰— is —CH₂CH₂— to form a 1-pyrrolidinyl group. The intermediate [C2] which is 1-(4-aminophenyl)pyrrolidin-2-one in this case, can be prepared by reaction of the compound [E] which is 4-iodoaniline in this case, with 2-pyrrolidinone, in the presence of N,N′-ethylenediamine, CuI, and dry K₂CO₃, using 1,4-dioxane as solvent at 110° C., based on the method described in International Patent Publication No. WO-2006/055951.

The intermediate compounds [1] that are prepared by these various methods in Scheme 9 can be converted to compounds of formula (I), where M is an amide group of type —N(R⁹)—C(O)R¹⁰, by using the coupling reaction methods that are described for Schemes 6, 7 and 8. Scheme 10 depicts an example for the synthesis of compounds which are encompassed by the structure of formula (I), where R³ is H and M is an amide group of type —N(R⁹)—C(O)R¹⁰. The synthetic method is similar to that described in Scheme 6, except that the final coupling step uses a boronic acid pinacol ester intermediate compound that is prepared as described in Scheme 9.

It will be recognized by those skilled in the art that in certain cases the groups R², R³, R⁷ and R⁸, as well as substituents on the groups R², R³, R⁷ and R⁸, can be modified to produce different groups R², R³, R⁷ and R⁸. The reactions to effect these modifications can be conducted during the course of the synthetic sequences that are depicted in Schemes 1 to 8. Alternatively, in certain cases the groups R², R³, R⁷ and R⁸, as well as substituents on the groups R², R³, R⁷ and R⁸, can be modified after the preparation of compounds of the invention of formula I, to produce additional compounds of formula I. Likewise, some substituents can be converted into hydrogen, to afford the corresponding derivative that is unsubstituted at that atom position. Examples of such reactions to convert one substituent into a different substituent include, but are not limited to: the reduction of an aldehyde or ester substituent to a hydroxymethylene group; the conversion of an aldehyde to form a secondary alcohol fragment; the conversion of an aldehyde or ester group to form a dialkyl tertiary alcohol group; the conversion of an aldehyde group to a methyl group; the conversion of an aldehyde group to a methyl ester group and then (at a later step) to an amide or carboxylic acid group; the conversion of an aldehyde group to a dimethylamino-methylene fragment; the conversion of an aldehyde group to a cyano group; and the conversion of an aldehyde group to a methyl ketone fragment. Examples of these conversions and the reaction methods that can be used in these cases are depicted in Schemes 11 & 12.

In Scheme 11, intermediate [GGG2] is prepared by using the methodology described in Schemes 6 and 7 (e.g., see Example 10, Step 1, in the Examples), and then methods a to h are applied to effect various modifications of the R² group. The resulting intermediates with these different R² groups are then converted to various compounds of the invention of formula (I) by methods that are well-known to those skilled in the art, and the methods described in Schemes 6 and 7. Examples of the reagents and conditions used for steps a to h in Scheme 11 are as follows: (a) NaBH₄, MeOH, rt, 1 h; (b) MeMgBr, THF, rt, 2 h; (c) i. NaCN, MnO₂, MeOH, 0° C.−rt, 3 h; ii. MeMgBr, THF, 0° C., 3 h; (d) i. NaCN, MnO₂, MeOH, 0° C.−rt, 3 h; (e) i.

The resulting intermediates with these different R² groups are then converted to compounds of formula (I) by methods described in Schemes 6. Examples of the reagents and conditions used for steps a and b in Scheme 12 are: (a) LiAlH₄, THF, 0° C.−rt, 5 h; (b) MeMgBr, THF, 0° C.−rt, 12 h.

Scheme 13 depicts the preparation of boronic acid pinacol ester intermediate [3], in which the synthetic methodology is similar to that used as described in Scheme 4, after the initial formation of the ester [B3] from the carboxylic acid [A]. The ester [B3] can be prepared by various methods known to those skilled in the art, such as by reaction of the acid [A] with methyl iodide in the presence of potassium carbonate, for example in DMF at room temperature for 2 hours. Reduction of the nitro group in [B3] to give intermediate [C3] is followed by steps c and d to provide the urea intermediate [O3] via the trichloroethyl carbamate intermediate [P3]. Alternatively, in certain cases the intermediate [C3] can be converted in one step to the urea intermediate [O3], by treatment with the appropriate isocyanate, for example by the method as described in Scheme 5. Conversion of urea [O3] to intermediate [3] is accomplished by using the same reagents and conditions as described in step e of Scheme 4.

As depicted in Scheme 14, the intermediate [BB1] from Scheme 6B, [BBB] from Scheme 6G, [JJ1] from Scheme 7A or [EEE1] from Scheme 8A can be treated with compound [1] in Scheme 13 by using PdCl₂(PPh₃)₂, Cs₂CO₃, DMF, H₂O at 90-95° C. for 2-3 h, or PdCl₂(PPh₃)₂, Cs₂CO₃, toluene, ethanol and H₂O at 90-95° C., for 2-3 h. The obtained ester intermediate [4] is then hydrolysed, for example using lithium hydroxide in methanol, THF and H₂O, at rt for 5-12 h. The resulting acid intermediate is then subjected to amide coupling with the appropriate amine R⁷R⁸NH, using amide coupling conditions that are well known to those skilled in the art, such as HATU, with DIPEA or TEA, in DMF at rt for 12 h; or EDCI.HCl, with HOBt, and DIPEA or TEA, in DMF at rt for 12 h to obtain the desired compounds encompassed by formula (I).

Pharmaceutical compositions useful herein contain a compound of formula (I) in a pharmaceutically acceptable carrier optionally with other pharmaceutically inert or inactive ingredients. In another embodiment, a compound of formula (I) is present in a single composition. In a further embodiment, a compound of formula (I) is combined with one or more excipients and/or other therapeutic agents as described below.

The pharmaceutical compositions of the invention comprise an amount of a compound of formula (I) or a pharmaceutically acceptable salt thereof that is effective for regulating the PI3K/AKT/mTOR pathway in a subject. Specifically, the dosage of the compound of formula (I) to achieve a therapeutic effect will depend on the formulation, age, weight and sex of the patient and route of delivery. It is also contemplated that the treatment and dosage of the compound of formula (I) may be administered in unit dosage form and that one skilled in the art would adjust the unit dosage form accordingly to reflect the relative level of activity. The decision as to the particular dosage to be employed (and the number of times to be administered per day) is within the discretion of the ordinarily-skilled physician, and may be varied by titration of the dosage to the particular circumstances to produce the desired therapeutic effect. In one embodiment, the therapeutically effective amount is about 0.01 mg/kg to 10 mg/kg body weight. In another embodiment, the therapeutically effective amount is less than about 5 g/kg, about 500 mg/kg, about 400 mg/kg, about 300 mg/kg, about 200 mg/kg, about 100 mg/kg, about 50 mg/kg, about 25 mg/kg, about 10 mg/kg, about 1 mg/kg, about 0.5 mg/kg, about 0.25 mg/kg, about 0.1 mg/kg, about 100 μg/kg, about 75 μg/kg, about 50 μg/kg, about 25 μg/kg, about 10 μg/kg, or about 1 μg/kg. However, the therapeutically effective amount of the compound of formula (I) can be determined by the attending physician and depends on the condition treated, the compound administered, the route of delivery, the age, weight, severity of the patient's symptoms and response pattern of the patient.

The therapeutically effective amounts may be provided on regular schedule, i.e., daily, weekly, monthly, or yearly basis or on an irregular schedule with varying administration days, weeks, months, etc. Alternatively, the therapeutically effective amount to be administered may vary. In one embodiment, the therapeutically effective amount for the first dose is higher than the therapeutically effective amount for one or more of the subsequent doses. In another embodiment, the therapeutically effective amount for the first dose is lower than the therapeutically effective amount for one or more of the subsequent doses. Equivalent dosages may be administered over various time periods including, but not limited to, about every 2 hours, about every 6 hours, about every 8 hours, about every 12 hours, about every 24 hours, about every 36 hours, about every 48 hours, about every 72 hours, about every week, about every two weeks, about every three weeks, about every month, and about every two months. The number and frequency of dosages corresponding to a completed course of therapy will be determined according to the judgment of a health-care practitioner. The therapeutically effective amounts described herein refer to total amounts administered for a given time period; that is, if more than one compound of formula (I) or a pharmaceutically acceptable salt thereof is administered, the therapeutically effective amounts correspond to the total amount administered.

The pharmaceutical compositions containing a compound of formula (I) may be formulated neat or with one or more pharmaceutical carriers for administration. The amount of the pharmaceutical carrier(s) is determined by the solubility and chemical nature of the compound of formula (I), chosen route of administration and standard pharmacological practice. The pharmaceutical carrier(s) may be solid or liquid and may incorporate both solid and liquid carriers. A variety of suitable liquid carriers are known and may be readily selected by one of skill in the art. Such carriers may include, e.g., DMSO, saline, buffered saline, hydroxypropylcyclodextrin, and mixtures thereof. Similarly, a variety of solid carriers and excipients are known to those of skill in the art. The compounds of formula (I) may be administered by any route, taking into consideration the specific condition for which it has been selected. The compounds of formula (I) may, be delivered orally, by injection, inhalation (including orally, intranasally and intratracheally), ocularly, transdermally, intravascularly, subcutaneously, intramuscularly, sublingually, intracranially, epidurally, rectally, and vaginally, among others.

Although the compound of formula (I) may be administered alone, it may also be administered in the presence of one or more pharmaceutical carriers that are physiologically compatible. The carriers may be in dry or liquid form and must be pharmaceutically acceptable. Liquid pharmaceutical compositions are typically sterile solutions or suspensions. When liquid carriers are utilized for parenteral administration, they are desirably sterile liquids. Liquid carriers are typically utilized in preparing solutions, suspensions, emulsions, syrups and elixirs. In one embodiment, the compound of formula (I) is dissolved a liquid carrier. In another embodiment, the compound of formula (I) is suspended in a liquid carrier. One of skill in the art of formulations would be able to select a suitable liquid carrier, depending on the route of administration. The compound of formula (I) may alternatively be formulated in a solid carrier. In one embodiment, the composition may be compacted into a unit dose form, i.e., tablet or caplet. In another embodiment, the composition may be added to unit dose form, i.e., a capsule. In a further embodiment, the composition may be formulated for administration as a powder. The solid carrier may perform a variety of functions, i.e., may perform the functions of two or more of the excipients described below. For example, solid carrier may also act as a flavoring agent, lubricant, solubilizer, suspending agent, filler, glidant, compression aid, binder, disintegrant, or encapsulating material.

The composition may also be sub-divided to contain appropriate quantities of the compound of formula (I). For example, the unit dosage can be packaged compositions, e.g., packeted powders, vials, ampoules, prefilled syringes or sachets containing liquids.

Examples of excipients which may be combined with one or more compound of formula (I) include, without limitation, adjuvants, antioxidants, binders, buffers, coatings, coloring agents, compression aids, diluents, disintegrants, emulsifiers, emollients, encapsulating materials, fillers, flavoring agents, glidants, granulating agents, lubricants, metal chelators, osmo-regulators, pH adjustors, preservatives, solubilizers, sorbents, stabilizers, sweeteners, surfactants, suspending agents, syrups, thickening agents, or viscosity regulators. See, for example, the excipients described in the “Handbook of Pharmaceutical Excipients”, 5^(th) Edition, Eds.: Rowe, Sheskey, and Owen, APhA Publications (Washington, D.C.), Dec. 14, 2005, which is incorporated herein by reference.

In one embodiment, the compositions may be utilized as inhalants. For this route of administration, compositions may be prepared as fluid unit doses using a compound of formula (I) and a vehicle for delivery by an atomizing spray pump or by dry powder for insufflation.

In another embodiment, the compositions may be utilized as aerosols, i.e., oral or intranasal. For this route of administration, the compositions are formulated for use in a pressurized aerosol container together with a gaseous or liquefied propellant, e.g., dichlorodifluoromethane, carbon dioxide, nitrogen, propane, and the like. Also provided is the delivery of a metered dose in one or more actuations.

In another embodiment, the compositions may be administered by a sustained delivery device. “Sustained delivery” as used herein refers to delivery of a compound of formula (I) which is delayed or otherwise controlled. Those of skill in the art know suitable sustained delivery devices. For use in such sustained delivery devices, the compound of formula (I) is formulated as described herein.

In addition to the components described above for use in the composition and the compound of formula (I), the compositions may contain one or more medications or therapeutic agents which are used to treat solid tumors. In one embodiment, the medication is a chemotherapeutic. Examples of chemotherapeutics include those recited in the “Physician's Desk Reference”, 64^(th) Edition, Thomson Reuters, 2010, which is hereby incorporated by reference. Therapeutically effective amounts of the additional medication(s) or therapeutic agents are well known to those skilled in the art. However, it is well within the attending physician to determine the amount of other medication to be delivered.

The compounds of formula (I) and/or other medication(s) or therapeutic agent(s) may be administered in a single composition. However, the present invention is not so limited. In other embodiments, the compounds of formula (I) may be administered in one or more separate formulations from other compounds of formula (I), chemotherapeutic agents, or other agents as is desired.

Also provided herein are kits or packages of pharmaceutical formulations containing the compounds of formula (I) or compositions described herein. The kits may be organized to indicate a single formulation or combination of formulations to be taken at each desired time.

Suitably, the kit contains packaging or a container with the compound of formula (I) formulated for the desired delivery route. Suitably, the kit contains instructions on dosing and an insert regarding the active agent. Optionally, the kit may further contain instructions for monitoring circulating levels of product and materials for performing such assays including, e.g., reagents, well plates, containers, markers or labels, and the like. Such kits are readily packaged in a manner suitable for treatment of a desired indication. For example, the kit may also contain instructions for use of a spray pump or other delivery device. Other suitable components to include in such kits will be readily apparent to one of skill in the art, taking into consideration the desired indication and the delivery route.

The compounds of formula (I) or compositions described herein can be a single dose or for continuous or periodic discontinuous administration. For continuous administration, a package or kit can include the compound of formula (I) in each dosage unit (e.g., solution, lotion, tablet, pill, or other unit described above or utilized in drug delivery), and optionally instructions for administering the doses daily, weekly, or monthly, for a predetermined length of time or as prescribed. When the compound of formula (I) is to be delivered periodically in a discontinuous fashion, a package or kit can include placebos during periods when the compound of formula (I) is not delivered. When varying concentrations of a composition, of the components of the composition, or the relative ratios of the compounds of formula (I) or agents within a composition over time is desired, a package or kit may contain a sequence of dosage units which provide the desired variability.

A number of packages or kits are known in the art for dispensing pharmaceutical agents for periodic oral use. In one embodiment, the package has indicators for each period. In another embodiment, the package is a labeled blister package, dial dispenser package, or bottle.

The packaging means of a kit may itself be geared for administration, such as an inhalant, syringe, pipette, eye dropper, or other such apparatus, from which the formulation may be applied to an affected area of the body, such as the lungs, injected into a subject, or even applied to and mixed with the other components of the kit.

The compositions of these kits also may be provided in dried or lyophilized forms. When reagents or components are provided as a dried form, reconstitution generally is by the addition of a suitable solvent. It is envisioned that the solvent also may be provided in another package.

The kits of the present invention also will typically include a means for containing the vials in close confinement for commercial sale such as, e.g., injection or blow-molded plastic containers into which the desired vials are retained. Irrespective of the number or type of packages and as discussed above, the kits also may include, or be packaged with a separate instrument for assisting with the injection/administration or placement of the composition within the body of an animal. Such an instrument may be an inhalant, syringe, pipette, forcep, measuring spoon, eye dropper or any such medically approved delivery means.

In one embodiment, a kit is provided and contains a compound of formula (I). The compound of formula (I) may be in the presence or absence of one or more of the carriers or excipients described above. The kit may optionally contain instructions for administering the medication and the compound of formula (I) to a subject having a disease characterized by the dysregulation of the PI3K/AKT/mTOR pathway.

In a further embodiment, a kit is provided and contains a compound of formula (I) in a second dosage unit, and one or more of the carriers or excipients described above in a third dosage unit. The kit may optionally contain instructions for administering the medication and the compound of formula (I) to a subject having a disease characterized by the dysregulation of the PI3K/AKT/mTOR pathway.

The compounds described herein are useful in regulating conditions which are associated with the PI3K/AKT/mTOR pathway. In one embodiment, such a disease is associated with abnormal cellular proliferation. The term “abnormal cellular proliferation” refers to the uncontrolled growth of cells which are naturally present in a mammalian body. In one embodiment, a disease which is characterized by abnormal cellular proliferation is cancer, including, without limitation, cancer of the prostate, head, neck, eye, mouth, throat, esophagus, bronchus, larynx, pharynx, chest, bone, lung, colon, rectum, stomach, bladder, uterus, cervix, breast, ovaries, vagina, testicles, skin, thyroid, blood, lymph nodes, kidney, liver, intestines, pancreas, brain, central nervous system, adrenal gland, or skin or a leukemia. In one embodiment, the disease characterized by abnormal cellular proliferation is cancer of the prostate.

The compounds of formula (I) regulate activity of mTOR and of PI3K. In a further embodiment, the compounds of formula (I) regulate PI3K activity. The tested compounds of formula (I) have the ability to inhibit all four isoforms of PI3K (α, β, δ, γ) with at least two of the compounds showing selectivity for the α PI3K isoform. These compounds associated with selective activity for the α isoform may be particularly well suited for treatment of conditions associated with the PI3K isoform, including, e.g., breast and gastric cancers, colorectal tumors, glioblastomas, and prostate cancer, and lung cancers.

In another embodiment, the compounds of formula (I) regulate the pathway of the PI3K-β isoform. In still a further embodiment, the compounds of formula (I) regulate the pathway of the PI3K-δ isoform. In yet another embodiment, the compounds of formula (I) regulate the pathway of the PI3K-γ isoform.

The ability of compounds to inhibit the PI3K delta and PI3K gamma isoforms has been described with the ability to treat acute and chronic inflammatory disorders. See, e.g., R C Camps et al, Nat Rev Immunol., 2007, Mar. 7(3): 191-201. Other inflammatory disorders have been associated more specifically with the PI3K delta isoform, including neutrophil-associated inflammation. Models for testing the ability of compounds to reduce inflammation in inflammatory arthritis are known, e.g., as described by Camps et al, Nature Med., 2005, 11, 936-943. Camps et al (2005) also describes models useful in assessing the ability of compounds to reduce inflammation in peritonitis. Models for testing the ability of compounds to reduce inflammation and/or improve healing after myocardial infarction are described by Siragusa et al, Circ. Res. (2010), 106, 757-768. A model for testing the ability of compounds to prevent bleomycin-induced pulmonary fibrosis is described by Wei et al, Biochem Biophys Res Comm. 2010, 397: 311-317 and Brent et al, Toxicology, 2000, 147: 1-13.

The term “regulation” or variations thereof as used herein refers to the ability of a compound of formula (I) to inhibit one or more components of a biological pathway. In one embodiment, “regulation” refers to inhibition of mTOR activity. In another embodiment, “regulation” refers to inhibition of PI3K activity. In a further embodiment, regulation refers to dual inhibition of mTOR and PI3K activity.

The utility of the compounds of formula (I) can be illustrated, for example, by their activity in the in vitro tumor cell proliferation assay described below. The compounds of formula (I) exhibit an mTOR and PI3K inhibitory activity, and therefore can be utilized in order to inhibit abnormal cell growth in which mTOR plays a role. Thus, the compounds of formula (I) are effective in the treatment of disorders with which abnormal cell growth actions of mTOR and/or PI3K dysregulation are associated, such as cancer.

In one embodiment, methods for regulating the PI3K and/or mTOR pathways are provided and include administering a therapeutically effective amount of a compound of formula (I) to a patient in need thereof.

In another desirable embodiment, methods for treating a disease characterized by an abnormal cellular growth resulting from a dysregulated PI3K/mTOR pathway are provided and include administering of a therapeutically effective amount of a compound of formula (I) to a patient in need thereof.

In a further desirable embodiment, methods for treating a condition treatable by inhibiting the PI3K/AKT/mTOR pathway are provided and include administering a therapeutically effective amount of a compound of formula (I) to a patient in need thereof.

As described herein, a therapeutically effective amount of a compound when used for the treatment of cancer is an amount which may reduce the number of cancer cells, reduce tumor size, inhibit metastasis, inhibit tumor growth and/or ameliorate one or more of the symptoms of the cancer. For cancer therapy, efficacy can be measured for example, by assessing the time to disease progression and/or determining the response rate.

As described herein, a therapeutically effective amount of a compound when used for the treatment of an inflammatory disorder is an amount which may delay the onset of or reduce the severity or duration of an inflammatory response, or which mitigates one or more symptoms of an inflammatory response. For treatment of an inflammatory disorder, efficacy can be measured, for example, by a reduction in physiologic signs of inflammation (e.g., redness, swelling, heat, loss of function) or by measuring changes in the levels of cells (e.g., monocytes, macrophages and other mononuclear cells) or molecules (e.g., pro-inflammatory cytokines) associated with inflammation.

The following examples are illustrative only and are not intended to limit the present invention.

Example 72 Biological Assays (i) PI3 Kinase Time-Resolved Fluorescence Resonance Energy Transfer (TR-FRET) Assay

The ability of compounds of the invention to inhibit PI3K activity was determined in a homogeneous TR-FRET assay using a PI3K assay kit (Millipore, USA; cat #33-016) according to manufacturer's instructions. PI3-Kinases (isoforms α, β, γ and δ) catalyze the phosphorylation of phosphatidylinositol, PIP2 to PIP3 in the presence of ATP and Mg²⁺. The PIP3 product is detected by displacement of biotin-PIP3 from an energy transfer complex consisting of Europium labeled anti-GST monoclonal antibody, a GST-tagged PH domain, biotinylated PIP3 and Streptavidin-APC. Excitation of Europium in the complex results in an energy transfer to the APC and a fluorescence emission at 665 nm. The PIP3 product displaces biotin-PIP3 from the complex resulting in a loss of energy transfer and thus a decrease in signal.

To test for the ability of compounds to inhibit the activity of PI3Kα (wild-type), exemplary compounds of formula (I) were dissolved in DMSO and directly distributed into 384-well plates at a volume of 0.5 μL. 14.5 μL of P110/P85a/PIP2 mixture in buffer (obtained from the Millipore kit) containing MgCl₂ (40 mM) and DTT (5 mM) was added to compound wells and incubated for 60 min at room temperature. P110/P85α was expressed in SF9 insect cells and purified nickel column extraction. Five ng of wild-type P110/P85α was used in the assay. The kinase reaction was started by the addition of ATP. The assay concentrations of both PIP2 and ATP were 10 μM. The reaction mixture was incubated for 30 min at room temperature and was terminated by the addition of stop mix and detection mix. Fluorescence was measured at 615 and 665 nm upon excitation at 340 nm in a Victor™ V5 fluorometer (Perkin Elmer, USA). The fluorescence emission ratio at 665 to 615 nm, proportional to the kinase activity, was plotted against the compound concentration to generate dose-response curves and IC₅₀ values were determined using GraphPad Prism® 5 software.

Inhibition of PI3Kα activity was observed for compounds of formula (I) as determined by this assay. See, Table 2.

The activity of PI3 kinase isoforms β, γ and δ were assayed in a similar manner to the assay protocol described above for PI3Kα, by substituting the appropriate p110/p85 isoform for the p110α/p85α. Compounds of formula (I) caused inhibition of PI3 kinase isoforms β, γ and δ as determined by these assays. For example, the compounds of examples 3, 51, 54, 111, 113, 115, and 253 each caused inhibition of PI3 kinase isoform β with IC₅₀ values<50 nM. The compounds of examples 104, 133, 146 and 152 each caused inhibition of PI3 kinase isoform β with IC₅₀ values<500 nM. The compounds of examples 3, 51, 54, 104, 111, 113, 115, 133, 253, and 152 each caused inhibition of PI3 kinase isoform γ with IC₅₀ values<500 nM. The compound of Example 2 caused inhibition of PI3 kinase isoform β and isoform γ with IC₅₀ values<1 μM. The compounds of examples 2, 3, 51, 54, 111, 113, and 253 each caused inhibition of PI3 kinase isoform δ with IC₅₀ values>1 μM.

The activity of PI3Kα mutations H1047R and E545K were assayed in a similar manner to the assay protocol described above for PI3Kα (wild type). The compounds of formula (I) caused inhibition of PI3Kα mutations H1047R (a mutation associated with breast and gastric cancers) and E545K (a mutation associated with colorectal tumors, glioblastomas, gastric cancers, breast cancers, and lung cancers). For example, each of the compounds of examples 1, 2, 3, 51, 54, 104, 111, 113, 115, and 253 caused inhibition of each of the PI3Kα mutations H1047R and E545K with IC₅₀ values<50 nM. Each of the compounds of examples 133, 146, and 152 caused inhibition of each of the PI3Kα mutations H1047R and E545K with IC₅₀ values<500 nM.

(ii) mTOR Kinase TR-FRET Assay

Compound inhibition for mTOR kinase was determined in a homogeneous TR-FRET assay using the Lance® ULight-p70 S6K (Thr 389) peptide (obtained from Perkin-Elmer). The ULight™-labeled synthetic peptide contains the amino acid residues surrounding Thr389 of human p70 S6K. The ULight-p70 S6K peptide is phosphorylated at Thr389 by mTOR. Phosphorylation motif: LGFTYVAP as substrate.

The compound dilution was carried out in 100% DMSO followed by a buffer dilution. The reaction buffer was HEPES (50 mM pH 7.5), EGTA (1 mM), MnCl₂ (3 mM). Test compounds at various concentrations were pre-incubated with mTOR (Millipore, USA; 5 ng) for 60 min, and then the Lance® ULight-p70 S6K (Thr 389) peptide (50 nM) was added along with ATP (20 μM). After incubating the reaction mixture for 60 min at room temperature, the kinase reaction was terminated by the addition of EDTA (10 mM) followed by the addition of detection mix, i.e., 1 nM Eu-labeled anti-phospho-substrate antibody (Perkin Elmer, USA). The fluorescence emission at 615 and 665 nM was measured upon excitation at 340 nM. IC₅₀ values were subsequently determined using a sigmoidal dose-response curve (variable slope) in GraphPad Prism® 5 software.

Compounds of formula (I) caused inhibition of mTOR kinase activity as determined by this assay. See Table 2.

(iii) In-Cell Western Assay

Cells from human prostate cancer cell line PC3 (American Type Culture Collection (ATCC), Manassas, Va. 20108 USA) were seeded at an optimal density of 22,000 cell/well in 96-well plates containing Ham's F12K medium (90 μL) and incubated overnight. The compound dilutions were carried out in 100% DMSO followed by a dilution in the medium. Test compounds were added in serial dilutions to the wells and incubated for 2 h. The cells were washed and fixed with 4% paraformaldehyde. After incubation at room temperature for 1 h in the dark, blocking was done for 2 h at room temperature. Primary antibodies for phosphorylated (p) AKT(5473) (phosphorylated at serine 473), pAKT(T308) (phosphorylated at threonine 308) and for pS6RP(S235/236) (phosphorylated at serine 235/236) (commercially available from Cell Signaling Technology®, whose protocol was followed for the in-cell western assay, were diluted to the required concentration and added to the corresponding wells followed by overnight incubation at 4° C. Eu-labeled rabbit (PE) (Perkin-Elmer USA catalog # AD0106) secondary antibody was added and incubated for 2 h at room temperature. Delfia® enhancement solution (cat #1244-105, Perkin Elmer USA) was subsequently added to the plate before taking the reading at 615 nm with excitation wavelength of 340 nm, after which 0.5 μg/mL of Hoechst® 33258 dye (Catalog #86140-5, Sigma) was added to the plate and fluorescence emission was read at 460 nm with 355 nm excitation, to evaluate the correction factor. IC₅₀ values were calculated using a sigmoidal dose-response curve fit in GraphPad Prism® v5 software. Compounds of formula (I) inhibited phosphorylation of Akt(5473), Akt(T308) and S6RP, as shown in Table 2. These results indicate the ability of the tested compounds to inhibit an PI3K/Akt-pathway dependent prostate neoplasm.

In-cell Western assays for pAkt(5473) and pS6RP are also carried out in a breast cancer cell line with PI3K mutations (PIK3CA-K111N mutation) which overexpresses HER 2 (BT474) cells and a human ductal breast epithelial cell line (T47D cells), in a similar manner to the protocol described above for PC3 cells, in order to assess the ability of the compounds to inhibit the Akt-pathway in two breast cancer cell lines. Compounds of the invention caused inhibition of pAkt(5473) and pS6RP in BT474 and T47D cell lines as determined by these assays. For example, the compound of Example 1 caused inhibition of pAkt(5473) in BT474 and T47D cell lines with IC₅₀ values<300 nM, and this compound also caused inhibition of pS6RP in BT474 and T47D cell lines with IC₅₀ values<50 nM.

(iv) XTT Assay for Cell Viability

Using a commercial kit from Sigma Aldrich (Catalog # X34251) and following its protocol, PC3 cells in the log phase of growth were employed and seeded at an optimal density of 1000 cell/well on to 96 well plates and incubated for 24 h followed by the addition of compounds of formula (I) in serial dilutions. Compound dilutions were made in DMSO. The cells were incubated with the compounds of formula (I) for 96 h and XTT tetrazolium dye (Sigma, USA) was subsequently added and incubated at 37° C. After the color formation, absorbance was measured at 465 nm in a Spectramax® Gemini spectrophotometer. EC₅₀ values were calculated using a sigmoidal dose response curve fit in GraphPad Prism® v5 software. The tested compounds of formula (I) which caused inhibition of PC3 cell proliferation as determined by this assay protocol are shown in Table 2.

XTT assays for cell viability are also determined in BT474 cells and T47D cells, in a similar manner to the protocol described above. The compounds caused inhibition of BT474 and T47D cell proliferation as determined by these assays. For example, the compound of Example 1 caused inhibition of BT474 and T47D cell proliferation with IC₅₀ values<100 nM.

(v) In Vivo Pharmacokinetic/Pharmacodynamic (PK/PD) Studies for Oncology

PC3 cells were cultured at 37° C. in a 5% CO₂ incubator using Hams F12 K medium. Ten million (10⁷) cells were injected subcutaneously to the right flank region of athymic male mice (Harlan, age: 6-7 weeks, weight: about 20 g). Tumor bearing mice were randomized when the tumor volume reached about 250 mm³ and three mice were used per each time point. Test compounds of formula (I) were formulated in 40% HPCD in 1×PBS, pH 7.4 and dosed orally at 50 mg/kg single dose (dose volume—10 mL/kg). Plasma and tumor samples were collected at 0 (vehicle control animals), 1, 4 and 24 hours post dosing. Blood was drawn (retro orbital) to a tube containing 0.2% EDTA for plasma collection. The tumor was excised from the mouse and immediately frozen in liquid nitrogen for PD analysis. Tumor and plasma drug concentrations were measured for PK analysis using LC-MS.

Snap frozen tumor samples were pulverized in a mortar (Belart) containing liquid nitrogen and tumor powder was stored at −80° C. until analysis. Pre coated ELISA kits (Cell Signaling Technology; pAKT(T308), CST#7135; pAKT(5473), CST#7134 and pS6RP, CST#7205) were used for PD analysis. Tumor powder was transferred to Eppendorf® tubes and lysis buffer (1 mL) was added to the powder. Protease and phosphatase inhibitors (SIGMA) and phenylmethanesulfonylfluoride (PMSF) were added to tumor powder and mixed by vortexing followed by sonication (15 sec). Samples were kept on an ice bath for 30 min. Supernatant was separated after centrifugation at 10,000 rpm for 20 min at 4° C. Supernatant was re-centrifuged and fresh supernatant was aliquoted to different tubes. Total protein was estimated using a BCA kit (Thermo Scientific) and 50 μg total protein was loaded to each well. ELISA analysis was carried out as per manufacturer's instructions. The detection for pAKT was based on chemiluminescence and pS6RP was based on absorbance. Qualitative assessments of the suppression of pAKT(T308), pAKT(5473), and pS6RP were also carried out by standard Western blot analyses.

The compounds caused suppression of pAkt and pS6RP as measured at 1, 4 and 24 hours after a single dose of 30-50 mg/kg po. For example, the compound of Example 1, at 50 mg/kg po, caused about 50% inhibition of pAkt(5473) at 1 and 4 hours and >50% inhibition of pS6RP at 1, 4 and 24 hours. Also, the compound of Example 2, at 50 mg/kg po, caused about 25-30% inhibition of pAkt(5473) at 4 and 24 hours and >50% inhibition of pS6RP at 1, 4 and 24 hours. The compound of example 51, at 30 mg/kg po, caused>50% inhibition of pS6RP at 2, 4 and 24 hours. Also, the compounds of examples 133, 146, 147, and 228, at 50 mg/kg po, each caused>50% inhibition of pS6RP at 3 and 8 hours. The compounds of examples 133 and 146, at 50 mg/kg po, each showed significant suppression of pAkt(T308) at 8 hours by Western blot analysis.

In vivo pharmacokinetic/pharmacodynamic (PK/PD) studies were also carried out using BT474 tumor cells and the corresponding tumor-bearing xenograft mice, and compounds of the invention were determined to be active in this assay. For example, the compound of example 51, at 30 mg/kg po, caused 30-40% inhibition of pS6RP at 4 and 24 hours. After dosing the compounds for 2 weeks at 40 mg/kg bid po, the compounds of examples 2 and 51 caused significant suppression of pAkt(T308), pAkt(5473) and pS6RP in tumor tissue samples by Western blot analyses.

(vi) In Vivo Efficacy Studies for Oncology (Tumor Growth Suppression)

PC3 cells were cultured at 37° C. in a 5% CO₂ incubator using Hams F12 K medium. Five million (5×10⁶) cells were implanted subcutaneously to the right flank of athymic male mice (Harlan, age: 6-7 weeks, weight: about 20 g). Tumor bearing mice were randomized when the tumor volume reached about 100 mm³. Ten mice were used per group. Dosage regimen of compounds of formula (I) were scheduled on the basis of the PK, PK-PD and maximum tolerated dose studies. Compounds of formula (I) were formulated using HPCD in PBS, pH 7.4 and dosed orally (dose volume, 10 mL/kg). Solutions of the compounds were prepared immediately before dosing the animals. A vehicle control and a reference compound were included along with test compounds.

The tumor size was measured on alternate days using Vernier® calipers. Assuming tumors to be ellipsoid, the tumor volume was calculated using the formula:

V=(D×d ²)/2

-   -   where:         -   V (mm³) is tumor volume         -   D is longest diameter in mm         -   d is shortest diameter in mm.

Changes in tumor volume (Δ volumes) for each treated (T) and control (C) group were calculated by subtracting the mean tumor volume on the first day of treatment (starting day) from the mean tumor volume on the specified observation day. These values were used to calculate a percentage growth (% T/C) using the formula:

%T/C=(ΔT/ΔC)×100

where ΔT>0, or

%T/C=(ΔT/ΔTi)×100

where ΔT<0 and Ti is the mean tumor volume at the start of the experiment.

Percentage tumor growth inhibition was calculated as [100−% T/C]. Percentage body weight change was calculated as [(Body weight on specified observation day−Body weight on starting day)/Body weight on starting day]×100. The compounds suppressed tumor growth in this in vivo efficacy model. For example, the compound of Example 1 caused more than 70% tumor growth inhibition as measured relative to vehicle control group, after 14 days of dosing at 60 mg/kg qd po or at 30 mg/kg bid po, and the compound of Example 2 caused more than 70% tumor growth inhibition as measured relative to vehicle control group after 14 days of dosing at 30 or 60 mg/kg qd po. The compounds of examples 82 and 183 each caused about 60% tumor growth inhibition as measured relative to vehicle control group after 14 days of dosing at 40 mg/kg bid po.

In vivo efficacy studies were also carried out using BT474 tumor cells, in a similar manner to the protocol described above for the PC3 tumor cell in vivo efficacy study. Compounds of the invention suppressed tumor growth in the in vivo BT474 efficacy model. For example, relative to vehicle control group after 14 days of dosing, the compound of Example 2 at 40 mg/kg bid po caused about 65% tumor growth inhibition, and the compound of example 51 at 40 mg/kg bid po caused about 70% tumor growth inhibition.
